ABSTRACT:
A fusion joining device for plastic tubes with which a pair of clampers30is supported such that it can be pivoted between the closed position where the joint portion T1is sandwiched from both sides through a pair of members for heat conduction20and the open position where the spacing between the pair of members for heat conduction20is widened; and a pair of heaters40made of a resistance heat generation material in the shape of a sheet is formed such that it is along the pair of members for heat conduction20, respectively, in order to heat the joint portion T1through the pair of members for heat conduction20.
